Is combustion of gasoline a physical change?
No, combustion of gasoline is a chemical change because it involves a chemical reaction between the gasoline and oxygen to produce carbon dioxide, water, and heat. A physical change involves a change in the physical state or appearance of a substance without altering its chemical composition.
What are two physical properties that could not be used to distinguish between water and ethanol?
Color and volatility
What properties could not be used to distinguish between table salt and table sugar?
color
Is not a physical property of water?
Perhaps the properties of space and time? Possibly the properties of a vacuum? You may be referring to "metaphysics" to distinguish between the real and the apparent properties of matter.
Is gasoline combusting a chemical or physical change?
Gasoline combusting is a chemical change because new substances are formed during the combustion process. The bonds between the atoms in the gasoline molecules are broken and rearranged to form new compounds, such as carbon dioxide and water vapor.
Is combustion of gasoline a physical change?
No, combustion of gasoline is a chemical change because it involves a chemical reaction between the gasoline and oxygen to produce carbon dioxide, water, and heat. A physical change involves a change in the physical state or appearance of a substance without altering its chemical composition.
Can you distinguish between a chemical and physical change?
they don't
Distinguish between nervous coordination and chemical coordination?
research
What is the relationship between the chemical properties of a substances and the chemical changes of a substances?
The chemical properties of an object show what a chemical change did to that substance.
What is the relationship between the chemical properties of a substance and the chemical change of substance?
The chemical properties of an object show what a chemical change did to that substance.
Is there a difference between chemical change and chemical properties?
yes
Which solvent oils are most soluble is it in gasoline water ethanol or benzene?
Benzene is the most soluble solvent in gasoline due to their similar chemical properties. Water is the least soluble solvent in gasoline as they are immiscible. Ethanol falls in between, being partially soluble in gasoline.
Is the burning of gasoline in a car a chemical change or physical change?
The burning of gasoline in a car is a chemical change because it involves a reaction between the gasoline and oxygen to produce new substances (carbon dioxide, water, and heat). This results in a change in the chemical composition of the substances involved.
What are the characteristic properties of matter?
Characteristics properties of matter are things such as:densitycolorsizeshapetemperatureThese are just few of hundreds of characteristics
Difference between chemical and physical change?
A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
Why is the burning gasoline in a car a chemical change?
Chemistry is just a subset of physics in general. A chemical event is the interaction of electrons of one atom with neighbouring atoms. For certain such interactions to take place, energy has to be added. Heat causes the molecules of gasoline to break apart and recombine with oxygen in the air. This in turn releases more energy, so the reaction continues around it as long as there is gasoline and oxygen available. Heat is really just "more frantically moving atoms". With sufficient movement, the energy causes chemical bonds, i.e. the configuration of electrons between atoms, to break or be made.
